No generalized rewrite rule found! ## Applying the DP framework... ## 1 initial DP problem to solve. ## First, we try to decompose this problem into smaller problems. ## Round 1 [1 DP problem]: ## DP problem: Dependency pairs = [f^#(_0,a(b(_1))) -> f^#(a(a(_0)),_1), f^#(_0,b(a(_1))) -> f^#(b(b(_0)),_1), f^#(b(_0),_1) -> f^#(_0,b(_1)), f^#(a(_0),_1) -> f^#(_0,a(_1))] TRS = {f(_0,a(b(_1))) -> f(a(a(_0)),_1), f(_0,b(a(_1))) -> f(b(b(_0)),_1), f(a(_0),_1) -> f(_0,a(_1)), f(b(_0),_1) -> f(_0,b(_1))} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... Failed! ## Trying with lexicographic path orders... Failed! ## Trying with Knuth-Bendix orders... Failed! Don't know whether this DP problem is finite. ## A DP problem could not be proved finite. ## Now, we try to prove that this problem is infinite. ## Could not solve the following DP problems: 1: Dependency pairs = [f^#(_0,a(b(_1))) -> f^#(a(a(_0)),_1), f^#(_0,b(a(_1))) -> f^#(b(b(_0)),_1), f^#(b(_0),_1) -> f^#(_0,b(_1)), f^#(a(_0),_1) -> f^#(_0,a(_1))] TRS = {f(_0,a(b(_1))) -> f(a(a(_0)),_1), f(_0,b(a(_1))) -> f(b(b(_0)),_1), f(a(_0),_1) -> f(_0,a(_1)), f(b(_0),_1) -> f(_0,b(_1))} Hence, could not prove (non)termination of the TRS under analysis. Proof run on Linux version 3.10.0-1160.25.1.el7.x86_64 for amd64 using Java version 1.8.0_292 ** END proof description ** Total number of generated unfolded rules = 534
